OIL LEVEL INDICATOR Filed Feb. 20, 1928 ll T'TOR/YB Fatented Get. 21,1930 JOHN warn, or LONG BEACH, CALIFORNIA O L- EVEL INDICATORApplication filed February 20, 1928. Serial No, 255,535.

This invention relates to an oil indicator cator which is simple inconstruction'and which is effective in operation. y Other ob ects,advantages, and features of invention may appear in the accompanylngdrawing, the subjoined detailed descriptions,

and the appended claim. I

In the drawing- Fig. 1, is an end elevation of my indicator. Fig. 2,- isa sectional view taken on line '22, Fig. I

Fig. 3, is a side elevation of my oil indicator with parts shown insection. Y

: Referring more particularly to the drawmg, the numeral 1, lndlcatesthe crank case of an enginewhich crank case is provided with a tappedopening 2,.in' which my indi-' cator is adapted to be mounted. Myindicator comprises a substantially L-shaped body 3,

which includes a horizontal chamber 4:, and a 7 vertical chamber 5. Athreaded extension 6, is provided extending from the chamber 4, whichextension screws into the tapped opening 2, thus the fluid in the crankcase 1,

flows into the chambers l, 5, to the samelevel' as in the crankcase.

A cap 7, screws onto the top of the body 3, over the chamber 5, and atube 8, screws into the cap 7. The tube 8, is closed at the top 40thereof, by a head- 9, whichscrews onto the top of the tube.

A float 10 is mounted in the vertical chamber 5, and isbut slightlysmaller than the diameter of the chamber, so that it is accuratelyguided in its movement up and down into the chamber.

A stem 11, rises from the float and is secured thereto, said stemextending into the tube 8. An indicator pin 12 is carried by the stem 11at its upper end and extends'into a slot 13 in tube 8 toindicate thelevel of the r 1 oil in the crank case.

Arcade 1A, is provided on the tube 8,'ad-

ja'cent the slot 13 so that the exactamount of oil in the crank case canbe determined.

For draining purposes I provide a plug 15,

in the side of the body 3. There is an advantage in providing theplug inthe side of .the body in that the indicator will not be loosened in theopening2, when the plug 15, is unscrewed.

V I have found my, indicator of particular I advantage in connectionwith the Pzickard;

motor car, to which it is particularly adapt-- "ed. If desired, atube8,'may be extended 5 any desired amount so that it will reach up 'to thedash in which, event the stem 11 is also lengthened, a correspondingamount and the indicating pin 12 will also appear on the dash.

Having described my invention, I'claim;

' An oil indicator for vehicle engines com; 5 prising an integrally castL-shaped body, a

threaded extension integrally formed on one end of said body and adaptedto screw into the crank case'of an engine, said body providing ahorizontalchamber and a vertical chamber therein, a cap mounted on theother end of the body over the vertical chamber, a tube mounted in thecap and ris- 7 ing therefrom, a head mounted on the top of the tube, afloat in the vertical chamber, which float is guided in said chamber bywalls thereof, a stem rising from-the float into the'tube, said tubehaving a vertical slot therein, and a pin projecting from-the stemthrough the slot, and a drainplug re movably mounted in the side ofthe'body and communicating with. the horizontal chamber. therein.

In testimony whereof, I affix my signature.v JOHN WALE.
